A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.

In electronics, TO-3 is a designation for a standardized metal semiconductor package used for power semiconductors, including transistors, silicon controlled rectifiers, and, integrated circuits. TO stands for "Transistor Outline" and relates to a series of …

TO56也就是说,TO底座的外径为5.6mm的一种封装方式。 主要的应用范围就是常规光器件，因为5.6mm大小适中，与常规的 SFP模块 、 XFP模块 结构均能够吻合，所以得到了巨大的发展。 目前主要应用于 LD-TO器件。 2、常规的TO46和TO52. TO46主要应用于 PD-TO。 其实早期PD也使用TO56，是因为光器件收端从焊接工艺切换为胶水工艺后，由于体积要求减少，而使用的TO46。 3、TO38. TO38封装主要应用与小型10G或者25G光器件，因为更小的体积可以制造出更小的 …

The TO-3 or TO3 is a type of 'metal can' package that is capable of high-power dissipation commonly used by power transistors, SCR's and other high-power semiconductor devices. The TO-3 is made entirely of metal, with the microchip mounted on its metal can base and then covered with a metal cap.

The TO 3 package, also referred to as TO 204AA is a metal can transistor package crafted for high power uses like power amplifiers, voltage regulators and audio devices.

1980 年，TO Can 封装的主要应用转向光电技术后，变得更加复杂。 通过其内部生产的光学玻璃及其特性，肖特开始提供传输光学信号所必需的 TO 光窗和透镜管帽。

本公司生产TO管座标准系列产品，包括TO3,TO5,TO8,,TO9,TO38,TO46,TO56TO60,TO66等管座，由于具备了批量生产条件，具有成本低、质量稳定、交货周期短等优势。

Hybrid TO-3s with isolated headers do not require electrically isolated pads. They can use electrically conductive pads. Without the need for a dielectric layer, a very low q CH can be achieved, almost as good as thermal grease.

TO-3 is a family of large through-hole metal can packages used for things such as transistors, linear regulators and op-amps. There are 2 lead (common), 3 lead (common), 8 lead (rare), and 15 lead (very rare) variants.

Options: open Headers and cans available for packaging live die. State your die size requirement.
